industrial roasters
the Saturn, Neptune and Jupiter production lines.

probat has been building roasters in germany since 1868, and they're the benchmark for industrial-scale production. machines are built heavy, designed for decades of daily operation, and engineered around repeatability at volume. the saturn and neptune sit at the high end of their lineup: fully automated drum roasters for operations running 30 kg batches and up. these aren't machines you tweak by hand. they're production workhorses built for multi-shift facilities where batch-to-batch consistency matters more than artisan flair. expect tight temperature control, automated profiling, and the kind of durability that makes them hold resale value better than most. probat's reputation comes from commercial bakeries, contract roasters, and high-volume operations that need to hit the same profile day after day without drift. if you're scaling past 100 kg an hour and need equipment that won't become a bottleneck, probat makes sense. if you're still dialing in single origins by feel, you're not the target buyer.
build quality and longevity. probat machines are engineered for decades of heavy use, not planned obsolescence. the drum design prioritizes even heat distribution and consistent bean movement, which matters when you're running the same profile across hundreds of batches. automation is genuinely tight: multi-point temperature sensing, real-time feedback, and profiling systems that don't drift between maintenance cycles. they also hold resale value better than most manufacturers, which matters when you're planning upgrades or selling used equipment. you're paying for german engineering that's proven in large-scale commercial environments.
batch size and throughput. the saturn handles 30 to 150 kg per batch, suitable for mid-to-large roasting operations that need serious daily volume but aren't running multiple shifts. the neptune starts at 60 kg and goes to 600 kg, built for contract roasters, large distributors, or facilities running continuous production schedules. both are fully automated gas drum roasters. if you're producing under 500 kg a day total, the saturn likely covers you. if you're planning multi-ton weekly output or already running smaller industrial machines at capacity, the neptune makes sense.
they're capable but not designed for constant experimentation. probat's strength is locking in a profile and repeating it precisely across thousands of batches. the automation handles most variables well once you've dialed things in, but if you're tweaking airflow and gas by hand every roast, you're working against the design. facilities that run a stable product lineup and need zero drift will appreciate the control. roasters who chase seasonal microlots and constantly adjust development curves might find the system less intuitive than more manual machines.
